Abstract
The present invention relates to an authentication system, a small base station, and an authentication method which allow a server side to authenticate whether an installation position of a small base station is valid or not. In a packet to be sent as an authentication request from the femto base station, in-IC card information of an IC card inserted into the femto base stationis contained. A network terminating deviceconverts a local IP address described in a header of the packet to a global IP address, and sends it to a femto concentrator. The femto concentratorgenerates authentication information by associating the in-IC card information with the global IP address, and sends it to an authentication server. The authentication serverdetermines that the installation position of the femto base stationis valid if the in-IC card information and global IP address included in the authentication information have been associated with each other and registered in an authentication table. The present invention can be applied to a base station for a femtocell.
